I read this the other day on Seth Godin's blog. I'm a bit of a fan of Seth Godin, and this is one of his best blogs.
Why, why, why do businesses fight change so much? With change, there is a huge opportunity for money - guaranteed. Seth's examples here are excellent and show that the world of business is somewhat ass-backwards in their thinking.
I was introduced to Seth Godin with this video. I highly recommend it.
